STANDARD CONSTRUCTION OF THE MESKER STEEL SASH 


SECTIONS 

The single bar sections for Mesker Steel Windows consist 
of one piece solid section rolled open hearth steel and gives 
maximum strength and rigidity, thoroughly weather-proof 
and neat in appearance. 


FRAME AND VENTILATOR BARS 

The outer members of the sash and ventilator frames 
comprising the top, bottom and two sides consists of ONE 
CONTINUOUS, SOLID SECTION STEEL BAR, BENT 
ROUND AT THE CORNERS (see engraving), and the two 
ends coming together is strongly spliced and welded. This 
continuous feature of the outer frame member makes the 
sash and ventilator at the four corners inflexible and unbreak- 
able. It also prevents the sash from becoming twisted and 
warped out of square. No other sash manufactured has this 
superior quality.

PIVOTS 
The Mesker pivot is patented. It is not a hinge or an 
attachment of any kind, therefore, no plates, bolts, nuts, 
pins, or other loose parts are required in its make up. It 
cannot rust tight when not in use. Its superiority lies in 
the simplicity of its formation.

vided on which the ventilator balances perfectly on its own 
axis and yields to the slightest touch of the push bar or 
chain operator. The pivot feature of the ventilator does not 
affect the alignment of the glass rabbets, they are as flat as 
the glass itself. The Mesker pivot permits the ventilator to 
be removed by window cleaners without the use of tools, 
and to be replaced without readjustment or refitting. 


VENTILATORS 


The weathering features of our ventilators are designed 
in accordance with the well-known principle of flat straight 
surface contact, overlapping the muntins three-eighth inch all 
around, which is preferable to the point or butt contact, 
making a continuous flat weathering, thoroughly rain proof. 
Ventilators are made entirely by machinery, assuring a 
closely-fitting, well-balanced sash, free from the uncertainty 
of hand labor, at the most important part of the window. 
Weep holes or drains are provided at sill of ventilator near 
the jamb, to carry off inside condensation. 


A fulcrum bearing is pro- 


When ventilators extend to both sides of window, keep 
sash slightly away from masonry to prevent ventilator from 
binding against the wall when opening. 


JOINTS 

The joining of horizontal and vertical muntins if formed 
by a special (patent applied for) dovetail wedge and miter. 
Where the muntins 
intersect the frame bar, 
a double two-way mor- joint aFTER ASSEM- 
tise and tenon feature is BLED, SHOWING 
employed, as shown by CAULKING FEATURE, 
engraving. The joints 
being interlocked by 
powerful presses gives 
the sash great strength 
against wind pressure. 
Hand power in the 
manufacture of our steel 
windows is entirely elim- 
inated, assuring a 
perfectly fitting and 
high-class article impos- 
sible of attaining by 
hand-made process,

PUSH BARS 

Push bar sash adjusters are furnished for all ventilators, 
unless otherwise specifically mentioned. They are made of 
heavy rolled bar iron, connected with strong eye bolt to steel 
angle bracket, securely fastened to bottom of ventilator. 
Notches in edge of push bar fit over edge of weathering 
angle, enabling the ventilator to be opened at any required 
position. When ventilator is closed the push bar is folded 
back, inserting its notches. into loops in weathering angle 
securely locking the ventilator.

The cam lock is of heavy steel construction, connected to

to bottom of ventilator. The chain is fastened to top of 
ventilator by heavy steel ring, and holds the ventilator open 
at any desired angle by fastening the chain to cleat on wall 
or to hook at bottom of sash.

gauge steel. They have the distinctive 
feature of matched tongue and groove 
boards, making them rainproof, wind- 
proof, and dustproof. Other superior 
qualities of our mullions are: 

They have no unsightly bolts and 
nuts, or expansion slots, to mar their 
appearance or cause trouble in erection. 

They have no seams to spread and 
admit water. They have two inches of 
continuous weathering contact. The 
tongue and groove feature provides for 
expansion and contraction, also for the 
most rapid installation at a reduction 
of 20% in cost. F 

See page 11 for illustration of tongue DUST-PROOF 
and groove mullions. They wary in SER PIES Stein oe 
width, from 3 inches up, as may be 
necessary to make up standard width cf masonry opening. 


HORIZONTAL MULLIONS 

Horizontal mullions of the design here 
shown are desirable where one sash is set 
immediately above the other, and may be 
built up of angles and channels combined. 
These are never furnished by us unless 
specifically agreed upon, and are here 
shown merely as suggestion and informa- 
tion. The size and weight of these struc- 
turals depend on the width of opening. 


MECHANICAL OPERATORS 

These devices can be furnished in con- 
nection with our warehouse and special 
sash at an extra charge. Sash can be 
arranged for their reception, but require extra time, as these 
operators are made to individual orders. 
GLASS SIZES 


Units are furnished in two standard sizes, for lights 
12 x18 inches and 14x20 inches. Note that the lights in

plain plate glass may be used. Adopting standard sizes will 
mean low cost and quick delivery, other sizes <a 
can be furnished at greater cost. All glass 
sizes should be rechecked. 


GLAZING 

Our glazing clips are of special design, 
devised to hold the glass firmly in place, four 
clips to each light. These clips take up the 
variation in the thickness of the glass. Spe- 
cial steel sash putty should be used. Ordi- 
nary putty dries out and breaks away. Spread 
putty on the glazing rabbet, force glass into 
same, completely filling the entire space 
between the glass and ie steel. Excess 
putty neatly struck off . glass face puttied.

PAINTING 


All sash receive one priming coat of paint before leaving 
our factory. 


UNLOADING 

Care must be exercised in unloading sash, lest they 
become damaged, making repairs necessary before installation. 
STACKING 

The sash should be stacked at building site in the manner 
shown by cut. They should never be laid flat. Lay three 


pieces of wood in level position, tilting sash against upright 
braces or lean them against building.

ERECTION 


We cannot guarantee sash to be satisfactory unless they 
are set plumb, true and straight in the openings, which 
latter must have the angles true 90 degrees, when any ordi- 
nary mechanics can install them at nominal cost. Place 
wood blocks directly under sash at points shown in illustra- 
tion and level the bottom of the sash, noting in particular 
that horizontal muntins line up with adjoining sash. 

The steel clips with which tke ventilator is fastened must 
never be removed until sash are ready for glazing. 

All ventilators are carefully tested before leaving the 
factory, but if adjusting should be necessary at the building 
it should be done before, not after sash are glazed. 


To install single units after walls are built, leave groove 
in jamb on one side of opening 114-inch wide, and 44-inch 
wide in the other jamb. Slip one edge of the sash into the 
larger groove, and then swing the other edge into the smaller 
groove. Adjust the sash evenly into the opening and block 
up the sash at the sill, and secure upper projecting flange of 
sash to lintel construction, see page 11, details H1, H3, HS, 
H7. Build sill under sash and grout sash all around to a 
neat finish. 


When opening has two or more units, allow Y-inch 
groove in masonry of each jamb. Set one sash flange into 
groove in either jamb and other flange into mullion. Follow 
in tongue and groove manner, alternating with mullion and 
sash, completing with sash flange inserted into 14-inch 
groove in opposite jamb. 


Block up sash at sill with upper sash flange entering 
lintel and build up sill under sash. Do not crowd sash, use 
care, remove obstacles, and the result will be 20% saving in 
erection cost with tongue and groove mullions. 

In concrete wails, a rebate should be formed in jambs. 
Install sash as directed above. Grout sash neatly all around.

COMMENT 


The weather side of our sash have a very neat finish, clear cut muntin 
lines, symmetry in appearance, and free from projections or flanges to 
catch dust, snow or other objectionable matter to hasten rusting. 

These steel windows are lower in price than wood and far more desir- 
able, considering volume of light area and ventilation, they are incom- 
parably superior. 

Customers are given the benefit of our very low prices, attained by 
purchasing material in large quantities at advantageous market quota- 
tions, by manufacturing sash at a ratio of 95% machine labor to 5% 
hand labor, and by the 33 14% less freight charges than cbtain in other sash.

THE MESKER SIDE ARM EXTENDING VENTILATOR SASH 


The Mesker Solid Section rolled open hearth Steel Sash with improved Side Arm Extending Ventilators ere especially adapted, and are being extensively 
used in Schools, Industrial and Office Buildings, or wherever a superior window with maximum ventilation is desired. They are readily adopted by Architects 
and School Boards for the most perfectly operating windows without projecting the sash into the rooms. When open, the ventilator serves either as a rain 


shield or as an awning as well as for ventilation.

VENTILATOR LI 


TYPE 
The Extending Ventilator opens out at the bottom, causing the top to slide 
down vertically. This is accomplished by means of a pull chain fastened at the top. 
which projects the ventilator outwardly at the bottom. The slam, heretofore 
experienced when closing other types of sash is entirely eliminated in the extend- 
ing type. 
The necessary friction for the successful operation of this type of sash is 
developed by our special construction of sash bar. Has no springs or bolts to be 
adjusted, but a vertical slide arrangement of utmost simplicity, requiring the least 
STANDARD SIZES effort to operate. 
The self balancing ventilator automatically adjusts itself to any angle, 
from the vertical to the horizontal plane, giving window cleaners full access to the outside of the glass. 
Another distinguishing feature of the Extending Ventilator is that it admits the attachment of window screens, on the interior as well as window 


shades and draperies. 


CONSTRUCTION 
The sash and ventilator is constructed of solid rolled open hearth steel section. The outer frame consists of ONE PIECE CONTINUOUS STEEL 
BAR, bent round at the four corners and welded at the splicing of the two ends. The muntins, also of solid steel section are tenoned at the ends and 
mortised into the frame members. And when caulked by heavy machinery makes the sash of greatest possible strength, and perfectly square and true, so that 
they cannot be racked out of shape by careless or rough handling. No other sash manufactured has this superior ONE-PIECE FRAME BAR FEATURE. 


MULLIONS 
The Mesker PATENT Mullions are designed to be used to join a multiple of units in large openings for lighting class rooms, auditoriums, hospital 


wards. etc. 
They are constructed of No. 14 or No. 16 gauge steel, and formed into the distinctive feature of matched tongue and groove boards, and are rainproof, 


windproof, and dustproof, 

They have no unsightly bolts, nuts or expansion slots to mar their appearance or cause time or trouble in erection. And no seams to spread open 
and admit dust and water. The tongue and groove feature provides for expansion and contraction and also for the most rapid installation at a reduction of 
20% in cost. See page 11 for special types of mullions designed to substitute stone, terra cotta or wood. These mullions may be -cz-rste filled and plaster 
finished on the interior and they-present on crchitectural finish on.the exterior *-2~ 1 
STANDARD SIZES 

The sizes of units for this type of sash are the same as for the standard center pivoted type. 
Customers sending inquiries regarding this type of sash should refer to unit numbers given. 9 
For high windows where an upper and lower ventilator is desired as in Nos. 501-502-503 it is recommended that the lower one extend in at the top 


and the upper one extend out at the bottom. ; : : ; ? 
One hundred percent ventilation is obtainable with the extending ventilator, but maybe opened to any desired angle without the use of push bar or 


any other fasteners. 


GLAZING 

Our glazing clips, of special design, are devised to hold the glass firmly in place. Holes are provided in the muntin bars for the clips—four or more 
to each light. The clips take up the variation in thickness of the glass. Special steel sash putty should be spread on the glazing rabbet and the glass forced 
into same, completely filling the entire space between the glass and the steel. Do not use ordinary putty, it dries out and breaks away. Excess putty should 
be struck off and glass face puttied. 


HARDWARE 
The extending ventilator is operated by an en 


to th. Sottom of ventilator. ; , ; 
Chains, pulleys, locks, etc., are included in our quotations. 


PAIN «ING

Showing Typical large area window for School Buildings; with the Mesker Patent Mullions combining several sash units. The 
heavy Steel Mullions have the appearance of stone or terra cotta and add to the Architectural beauty of the structure. In the 
Mesker Solid Section School Window is found a most desirable means for day lighting large Halls, Class Rooms, and Auditoriums, 
and is being largely adopted by Architects for this purpose. The Mesker Patent Mullion may be plain or moulded into artistic 
design to represent cut stone and to carry into effect the general appearance of the building.

BRICK CONSTRUCTION BRICK, PLASTER FINISH. IS S CONCRETE CONSTRUCTION WOOD CONSTRUCTION 


The Mesker Steel Basement Windows are made in two sizes and are constructed of solid rolled open hearth steel sections 
throughout, %” thick. The outer frame bars of the sash and ventilatcr are made of ONE CONTINUOUS PIECE OF SOLID 
ROLLED STEEL SECTION welded together at the ends. This makes the sash of greatest possible strength, and perfectly 
square and true, so that they cannot be racked out of shape by careless or rough handling. No other sash manufactured 


has this superior ONE-PIECE FRAME BAR FEATURE. 


To install Basement Windows the mason lays four or five courses of brick, leaving a half inch groove in the brick jamb on 
each side. Slide the sash down into these grooves, the projecting flanges of the sash extending into the grooves. Then build up 
the walls encasing the sash flanges into the brick work, and neatly point up with cement mortar all around. In concrete walls a 
rebate should be formed in each jamb and the sash is slipped down from the top into the rebate and grouted securely. 


The Mesker pivot is patented. It is not a hinge or an attachment of any kind, therefore no plates, bolts, nuts, pins or other 
loose parts are required in its make up. It cannot rust tight when not in use. Its superiority lies in the simplicity of its forma- 
tion. The Mesker Pivot permits the ventilator to be removed by window cleaners without the use of tools, and ts be replaced 
without readjustment or refitting. 


The lock is of heavy steel securely riveted to ventilator. A slotted seat is pressed into the frame for latching and insures 
absolute weathering. There are no springs, bolts or nuts to rust or get out of order. 


Steel glazing clips to hold the glass in position are furnished. A good grade of steel sash putty should be used. Putty 
should be spread upon the glazing rabbet and the glass forced into same, completely filling the entire space between the glass and 
the steel. Face putty the glass and neatly strike off excess putty. 


Our basement windows come complete ready to install in brick, stone, concrete or wond walls. They are serviceable, econom- 
ical, easy to operate> Thé ventilator is pivoted at the top and swings in at the bottom and can be fastened to ceiling. When 


“ open 100% ventilation is obtained. 


They have more lighting capacity than wooden windows, better in appearance, they are fireproof, they cost less and they 
last longer. 

The Mesker Basement Windows are easily installed, the flanges of the frame extend into the masonry, and they are built 
in as the walls go up. The steel flange along the top rail extends up into the lintel construction, and the lower rail is grouted into 
the window sill on the inside. These windows have a priming coat of paint before leaving the factory. 


Standard wooden screens may be used with basement sash from the outside. See detail above.

Clear, colored or translucent glass may be used for such artistic effect as may be adapted to carry out the desired design. 

INTERIOR FINISH—Since wood interior trim is not considered a necessity in modern homes, and as sanitation is being more carefully observed in building 
construction, plaster finish is preferably recommended for sides, head and sill of the interior where the Mesker Casement Windows are used. 
WEATHERSTRIPPING— Our (patent applied for) metal weatherstripping attachment to solid section steel sash is of the utmost simplicity and cost les 
weather stripping wooden windows and much neater in appearance, and prevents rattle, and is rainproof, windproof, and dustproof. The cost is only 

extra. Weather strips may be preferred for their neat appearance, softness of closure and air tight qualities. They are made of No. 11 gauge zinc, « 

gauge spring bronze and furnished only when ordered. Weather strips may be attached to our casements by owners subsequent to receiving the wind< 

may be attached without the assistance of a skilled mechanic before glazing. No practical method has been previously designed for fastening ™ 

strips to steel sash. ‘The means employed in the Mesker method is of utmost simplicity and practicability. With this latest achievement in wi 

no triple contact is necessary since the weather strips are secured to the sash. The Mesker metal weather stripped, air tight, casement 

rival for their artistic beauty and superior qualities. Weatherstripping not included in above prices.

The Mesker Steel and Glass Partitions are intended for office enclosures on the interior of mills, factories, garages, warehouses, machine shops, office 
buildings, department stores, balconies, banks, etc. They are fireproof, durable, easy of erection, inexpensive and they present a fine appearance. 

These partitions are made up of standard units of solid rolled section steel sash, designed to be artisticaily grouped with the Mesker tongue and 
groove mullions for any condition, dimension, or arrangement of plan. Partitions designed from our standard sizes, given on page 10, can be delivered 


from stock and at much lower prices than when specially designed. 
The wainscoting portion of these partitions are paneled with heavy steel plate, and the upper panels are glazed with ribbed, florentine, wire, plate 
or window glass. 
Partitions should be, as far as possible, 


When arranging for steel partitions, it is advisable to avoid coming in direct line between existing columns. 


run clear of any obstruction. 
The partition illustrated above is approximately 7 feet high, leaving ample space for the circulation of air and heat. Where it is desired, the 


entire enclosure may extend up to the ceiling by filling the space between the sash and ceiling with metal lath and plaster, or with steel plates. In such 
construction the mullions should run from the floor to the ceiling. In most cases, it would be impractical to extend sash to ceiling and fit around sprink- 
ling systems, steam pipes, beams, girders, and other obstructions contiguous to the ceiling. Ventilators may be placed in the sash at any desired location. 
The Mesker design of mullions makes it possible to readily remove partitions, which so often is required, and permits them to be taken apart. No 
be"*+ nuts or pins to be removed. Any or all units may be re-erected without removing the glass. 
Doors are manufactured from heavy rolled open hearth steel, welded at joints. Latches or locks and bolts are provided where needed. Doors 
vor frames are not drilled for hinges or door checks. This should be done by the contractor erecting doors to insure correct fit. 
An~ ordinary mechanic may install the Mesker Partitions with utmost simplicity, they fit like matched tongue and groove flooring after starters 
At wall and floor. Send sketch or plan of your requirement, showing existing walls and outline of partition needed, with full dimensions.

TY PES—The most desirable types in this class cf window are the Double Hung (or counterweighted) and the Count®enlanced Windows. These are especially 
suited for Business, Educational, Institutional, Industrial, Public, Residential and Recreational Buildings. 

UNDERWRITERS LABELED—These windows are subject to the rigid requirements and inspection of the National Board of Fire Underwriters, bearing 
their label of approval and accepted by rating bureaus everywhere in the United States and Canada as Standard Underwriters’ Windows. 
NON-LABELED—The non-labeled windows ere of the same construction as the iabeled, ex-ept that the glass in the non-labeled windows is held in place with 
steel giazing clips and putty, instead of steel glazing angles. 

CONSTRUCTION— The heads, 3 ills and jambs of the windows are made of No. 16 gauge steel, or No. 24 gauge galvanized steel. Grooves are formed in the 
frame to receive the projecting flanges of the sash members. The sash operates in the grooves with a vertical movement and insures easy operation and is 
perfectly weathertight. 

ACCESS TO WEIGHTS, DOUBLE HUNG WINDOWS—The grooved members of the jamb in the Double Hung Window are adjustable for the double 
purpose of removing the sash should occasionr equire, and for giving access to counter-weights after the window is installed. 

COUNTERBALANCED WiNDOWS—This type is recommendedi n preference to the Double Hung type. The frames are constructed of No. 16 gauge steel 
with grooves formed to receive the flanges of the sash members. The grooves permit perfect weathering and easy operation ofthe sash. The two sash counter- 
balance each other being hung on chains which pass over pulleys in the head. When open, the window allows 50% ventilation, heated air escapes through the 
top, and fresh air is admitted through the opening at the bottom. 

CONNECTION LUGS—The sill and head is secured to the jambs by a series of angle lugs riveted to the sill and head and fastened to the jambs by tap 
screws threaded into the lugs. (See illustrations.) 

MAY BE KNOCK DOWN —These types of windows may be furnished KNOCK DOWN form, thereby saving a considerable amount in freight cost. When 
so ordered, they are shipped in parts and assembled on the job. The cost at the factory is less. The cost of assembling at building must be added. The 
subsills are filled with concrete at the building. Instructions for assembling accompanies each order. 

SASH CONSTRUCTION—The sash is constructed cf solid rolled open hearth steel section. The outer frame consists of ONE PIECE CONTINUOUS 
STEEL BAR, bent round at the corners and welded at the splicing of the two ends. The muntins are also of solid steel section, mortised at the ends and 
tenoned into the frame members. making the sash perfectly rigid and cannot warp out of square.—Continued on page 13.
